A '''Berg connector''' - later known as a '''DuPont connecor''', or '''IDC connector''' ('insulation-displacement contact') - is a very common family of computer connectors.

They use pins in parallel rows, with .1 inch pitch (both betweeen row for multi-row connectors, and between pins).

The originals used 'male and female' plasic shells and pins: male pins in female shells (which went on [[printed circuit board]]s using [[Dual Inline Package|through-holes]]); and female pins in male shells, which went onto the ends of cables. with individual female shells crimped onto the wires of the cable.

In fairly short order, the physically compatible IDC connector was developed; it crimps onto [[flat cable]], making cable production much faster, easier, and more reliable.

The connectors which go onto boards are now often called 'headers', and they are available in 'straight' (the pins point up) and 'right-angle' (the pins point sideways) form; the crimp-on connectors are now available in male and female forms.

==Pin numbering==

Original Berg connectors were 40 pin, with the pins 'numbered' from the [[DEC alphabet]], from 'A' to 'Z' (an extension of the classical, which stopped at 'V'), and then 'AA' to 'VV'. '''''Facing''''' the pins in the header, with the PCB at the bottom, pin A is on the left, at the bottom, with 'B' above it, etc.

IDC connector come in a large variety of sizes (from 1 pin to 64, and perhaps larger), with one, two or three rows of pins. The pins are now identified by numbers; With the header in the orientation as above, pin '1' is in the upper right corner, with pin '2' immediately below it.
